Introduction

I found this equation on the internet and decided to plot it:

\[z = cos(x^2 + y^2)\]

The result was not as funny as I thought it would be, but I already named the document and I don’t want to change it.

This document was created in:

Sys.Date()
## [1] "2018-09-18"

Graphic

library(plotly)
source("R/funny.plot.R")
funny.plot()

Code for the plot is available in the github repository.
